Hi,I forgot my password to my wallet in bitcoin qt v.0.13 new,and try change but no result.After I open pywallet.py --web,and change passphrase , in localhost was written done!,and I stop pywallet --web.After I open bitcoin qt , and password dont changed.What you may help in this situation?
It is very difficult to understand what you are saying, but it seems you don't know your password. pywallet can't change your password if you don't know it to unlock it. That would be a huge security hole.
This isn't a pywallet issue, it is a you not knowing your password issue.
